UNITED STATES PATENT OFFICE.

LANT-ERN.

Application led April 2, 1925 To aZZ whom it my concern:

Be it known that I, CHAnLEs A. BREEN, a citizen of the United States, residing at Moose Lake, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Lanterns', of which the following is a specification, reference being had to the accompanying drawings. f

This application is for the subject matter of my prior abandoned application, Serial No. 33,175, filed June 9, 1915, for lanterns, and the invention relates to new and useful improvements in lanterns and as its principal object aims to provide a. novel form of adjusting mechanism for the chimney, whereby the same may beeasily and quickly swung from position over the lamp wick to an outJJf-the-way position to permit the cleaning or trimming of the wick.

Another and more specific object of the invention is to provide a lantern chimney adjusting mechanism which is so designed that it maybe operated to first lift the cap from over the chimney, to immediately and subsequently lift the chimney and dispose its lower terminal above the burner of the lamp, and to then swing the chimney out of the lantern frame. f

kThe above and other incidental objects of a similar nature, which will be hereinafter more specifically treated, are accomplished by such means as are illustrated in the accompanying drawings, described in the following speciication, and then more particularly pointed out in the claim which is appendedhereto and forms part of this application. A

f With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts,

Figure 1 is a front elevation of a lantern embodying the features oi my invention, and indicating in dotted lines the position which the lamp chimney assumes when operated upon by the adjusting mechanism to swing it out of the lantern frame;

Figure 2 is a section on the line 2-2 of .Figure 1;

Figure 3 is a detail view in longitudinal section, illustrating the manner in which the Serial No. 20,302.

tern is illustrated as an operative entirety.

In this figure, the lantern which is of conventional design, is shown as including a base 10; a substantially rectangular trame 11, which rises from the base a vertically adjustable cap 12, which is adapted to normally engage over lthe ends of the chimney 13, for holding this member in the proper position over the burner 14, and a bail 15, by means of which the lantern may be transported.

The elements ot construction above enumerated are all of conventional and standn ard design and since they do not form any part of the present invention, need not be further described in detail.

Upon one of the vertical members of the trame 11, is slidably mounted a sleeve'l, which member is preferably formed from a metallic tube of brass or other sheet metal.

Extending laterally from the upper terminal of the sleeve is a hoop 17, and from a point adjacent the lower terminal of the sleeve, extends a hoop 18. Each of these hoop members is formed preferably from a single length of wire of relatively heavy gage. The two terminal portions of the upper hoop arev extended laterally Jfrom the chimney, as indicated at 19, and are then bent downwardly at right angles, as at 20. At the lower terminals of the depending portions 20, are formed the coilsV 21 and from these coils the horizontal portions 22 extend to the sleeve. The horizontal portions 22 are coiled about the sleeve 16, as indicated at 2 2 and are freely engaged with the sleeve so that the sleeve may slide within the coils for a purpose which will hereinafter become apparent.

As will be readily observed upon reference to Figure 1, the upper hoop is adapted to embrace the upper terminal of the chimney. The two portions of the lower hoop are extended outwardly in a horizontal plane, as at 23, and are then directed upwardly and at right angles, as at 24. The upper termi nals of these portions 24: are directed outwardly at 25 and coiled about the sleeve.

One convolution of the coil is, as shown best in Figure 1, provided with a vertically extending loop a, which surrounds a stud or pin Z) carried by the sleeve 16. The coiled portions of the members 25 are freely slidable on the sleeve and are held against rotation thereon by iiieans of the stud b, which as shown in'Figure 1, engages with the arms of the loop a to prevent the turning of the coils upon this sleeve.

It is now to be explained that the hoop member 18 may be expanded against the tension of the wire from which it is formed, to permit a new lamp chimney to be introduced, whenever occassion may demand. It is also to be explained that the hoops are adapted to grip the chimney with sufficient force to support this member when the chiinl ney is moved out of the lantern frame in the manner disclosed in Figure 1.

A horizontal stop pin or equivalent device, indicated at 26, is carried by the vertical arm of the frame 11, upon which the sleeve is mounted so that this member will be limited in its downward sliding movement. A handle, indicated at 26, is applied to the sleeve 16.

When the sleeve is manipulated in a manner to be hereinafter explained, to swing the chimney out of the lantern frame, it is of course, requisite that the vertically adjust able cap 12 be elevated and disengaged from the upper terminal of the chimney before this member can be swung outwardly. For this reason, the cap 12 is connected t0 the upper end of the sleeve 16 by means of the arm 27 formed of wire or a small rod. The outer end of this arm 27 is passed around the lower end of the cap, forming an embracing hoop and is directed outwardly in a horizontal plane for a short distance as in Figure 1. r)The wire is then directed downwardly, as at 28 and thence outwardly, as at 29, and .finally coiled about the upper end of the sleeve, as illustrated in detail in Figure 3. An annular groove or recess, indicated at 30, is formed in the sleeve so that the attached terminal of the arm 27 will freely receive the sleeve to permit of rotation of the sleeve with respect to the arm, but will be held against vertical movement on the sleeve.

The actual construction and arrangement vof the several parts of the invention, being thus disclosed, it now remains to describe the manner in which the chimney adjusting `inechanism `may be manipulated to swing the chimney out of the frame. In this connection, reference will now be had particularly to Figure 1. As therein shown, the

operator may1 by lifting up on the handle i 226, cause the cap 12 to be first lifted and disengaged from the upper end of the chimney by means of the arm 27. As shown in Figure 1, the initial opening movement of the sleeve, during the lifting of the cap 12, will not affect the position of the chimney 13 for the hoop or wire 18, which controls the lifting of the chimney is not acted upon by the sleeve, until the cap 12 has been lifted a sufficient distance to disengage it from the upper terminal of the chimney. Obviously, the continued upward movement of the sleeve 16, after the stud b has been engaged with the top of the loop a will cause the chimney to be lifted so as to dispose its bottom edge above the burner of the lamp. During the lifting of the chimney, the cap, of course, continues its upward movement and, therefore, remains disengaged from the upper end of the chimney. After these two steps of lifting the cap 12 and subsequently lifting the chimney 13 to position above the burner have been coinpleted, the handle 26 may be turned to rotate the sleeve 16 with a consequent removal of the chimney from the lantern frame. The chimney may, in this manner, be swung to an out-of-the-way position, to the side of the frame, as indicated in dotted lines in Figure 1.

While I have found the bending of the hoop forming wires in the manner above explained, to be productive of the greatest efficiency in the construction of the lamp, I desire to explain that under some circumstances, particularly when tlie lamp is of a different construction from that shown in the accompanying drawings, various minor changes may be made in the specific shape of the hoop wires.

If .desirable,a hoop indicated ai 31, may be provided to surround the chimney immediately above the base thereof, as in Figure 1. rhis hoop is secured at one side to the member 24 and is accompanied at a diametrically opposite point, by a vertical post 32, which is connected to the member 18, as in Figure 1.

In reduction to practice, it has been found that the form. of this invention illustrated in the drawings, and referred to in the above description as the preferred einbodinient, it is the most eliicient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in the details of construction, proportion and arrangement of Lparts may be resorted to, when required, without sacrificing any of the ad vantages of this invention, as defined by the appended claim.

What is claimed, is

A lantern including a frame, a sleeve mounted to slide thereon upon a portion of the frame, a vertically movable chimney engaging cap, an arm engaging the cap and embracing the sleeve, a member carried by angles, the lower terminals of the dependthe sleeve adapted to engage the base of a ing portions being formed into coils and then 10 lamp chimney, and a loop adapted to emextended at right angles to the depending brace the upper terminal of the lamp chimportions and formed into loops, said loops 5 ney, said loop comprising a strand of maembraeing and freely engaging the sleeve.
